Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] like Figure 1-3 As shown, the present invention is a thermal insulation method for a mine slope road, comprising the following steps:

[0032] Step 1, introducing outdoor air into the preheating device for preheating;

[0033] In step 2, the preheated air enters the heating device for heating, and the heated hot air is mixed with the high-temperature steam introduced in the heating device to form a hot air of 51°C-57°C;

[0034] In step 3, the 51°C-57°C hot air heated and mixed by the heating device is sent into the air outlet device, and then leads to the mine slope road through the air outlet device;

[0035] Step 4: The hot air entering the slope road of the mine by the air outlet device is fully mixed with the cold air entering the slope road by negative pressure, and the hot air with the mixed air temperature ≥15°C is obtained.

[0036] The preheating d...

Abstract

The invention discloses a heat preservation method for a mine slope road. The heat preservation method comprises the following steps that firstly, outdoor air is introduced into a preheating device to be preheated; 2, the preheated air enters a heating device to be heated, and heated hot air is mixed with high-temperature steam introduced into the heating device to form hot air at the temperature of 51-57 DEG C; 3, the 51-57 DEG C hot air heated and mixed by the heating device is fed into an air outlet device and introduced into the mine slope road through the air outlet device; and 4, fully mixing the hot air introduced into the mine slope road by the air outlet device with the cold air entering the slope road by negative pressure to obtain the hot air with the mixed air temperature of more than or equal to 15 DEG C. The method is mainly used for mine slope roads, the problems that roads are frozen in winter, and potential safety hazards exist in personnel and vehicle passing are solved, the vehicle passing efficiency is improved, and timely supply of production material data is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mine engineering, in particular to a heat preservation method for a mine slope road. Background technique [0002] Mine slope road is an important facility for mine construction. It is not only the passage for workers, vehicles, equipment and materials to be transported up and down, but also the air inlet of the mine ventilation system, which is responsible for the task of delivering fresh air to the mine. [0003] Due to the frequent up and down of workers and vehicles at ramp crossings, ramp crossings are generally open for work convenience. In the northwest region, the winter is long, and it generally takes 5 months of severe cold weather. The extreme minimum temperature is around -20°C, and the average temperature is around -10°C. In the severe cold season, the slope roadway about 300 meters down from the slope crossing is seriously fogged and condensed due to the convergence of cold and hot air and ...
